Simple explanation
- Wi-SUN is an IPv6-based wireless field-area network standard for utility-scale mesh communication.
- It is designed for large endpoint populations where reliability and interoperability matter more than peak throughput.
Why it exists
- Utilities needed a standards-led alternative to proprietary RF mesh silos.
- Wi-SUN enables multi-vendor ecosystems with consistent protocol behavior.
Final takeaway
- Wi-SUN is best viewed as infrastructure architecture, not just radio technology.
